We see loads of testosterone supplement ads on TV nowadays, all of them claiming that if you don't have the zip, the pep, the bounce in your step, or the desire in the bedroom you used to have, maybe you could use some extra testosterone to help you get it back. And since testosterone comes from you-know-where (your balls), how about a zippy, peppy slogan to connect the dots?
So how about this for a testosterone supplement slogan: "Make your gonads go go go!"
No? Don't like that one? Well, then how about: "Puts the 'go' back in your gonads!"
